摘要

The steel has good workability and a completely stabilized structure, and contains: C, is not >0.03%; N, is not >0.03%; Cr, 17-25%; Ni, is not >0.5%; Cu, is not >0.2%; Si, 0.3-0.6%; Mn, 0.3-0.3%; Mo, 1-4% together with elements which are stabilizers and bind themselves to carbon, e.g. Ti-Nb/Ta, Al, Zr, there being >0.2% Ti.
